Which of the following expansion slots is 64-bit?
Click on the arrows to vote for the correct answer
A. B. C. D.D.
The correct answer is D. PCIe (PCI Express) is a 64-bit expansion slot.
Here's an explanation for each of the options:
A. PCI-X (Peripheral Component Interconnect Extended) - This is a 64-bit bus that is an extension of the original PCI bus. However, it is not as common as PCIe and has largely been replaced by it.
B. PCI (Peripheral Component Interconnect) - This is a 32-bit bus and is not 64-bit.
C. ISA (Industry Standard Architecture) - This is an old expansion slot that was used in early computers. It is a 16-bit bus and is not 64-bit.
D. PCIe (PCI Express) - This is a high-speed serial bus that can operate in various lane configurations, including 64-bit. It has largely replaced the older PCI and PCI-X standards in modern computers.
In summary, the only expansion slot among the options that is 64-bit is PCIe.
